TO VITUS ATTACHMENT FOR FIREARMS.

Specification of Letters Patent.

Patented Feb. 25, 1908.

Application filed May 1. 1907. Serial No. 371.252.

.ject to provide a fire arm with'a novel sight that can be easily and quickly adjusted for the varying distances of the ranges at which the fire arm is employed.

My invention aims to provide an attachmentparticularly designed for rifles, espe cially those used for long range shooting. To this end, I employ a telescope of a conventional form which can be easily and quickly adjusted, whereby a person can aim the rifle with precision, even though the object be a considerable distance away.

The detail construction entering into my invention will be hereinafter more fully described and then specifically pointed out in the appended claims, and referring to the drawing forming. part of this application, like numerals of reference designate corresponding parts throughout the several views,

in which Figure 1 is an elevation of a rifleequipped with the'improved attachment, Fig. 2 is a longitudinal sectional view enlarged of a portion of the attachment, Fig. 3 is an elevation of the adjustable portion of the improved attachment, showing the telescope partly broken away, Fig. 4 is a plan of a portion of the structure shown in Fig. 3, Fig. 5 is an end view of the rear sight of the attachment, Fig. 6 is an end view enlarged of the telescope associated with the attachment, Fig. 7 is an end view enlarged of a portion of the rear portion of the attachment.

The attachment is constructed of a plate 1 having depending rigid arms 2 adapted to embrace the barrel 3 of a fire arm 4. The

arms 2, as illustrated, are for a barrel hexagon-shape in cross section, but these arms can be made semi-cylindrical to embrace a cylindrical barrel. The arms are clamped to the barrel 3 by set screws 5.

The plate 1 is provided with side plates 6 having their inner sides provided with longitudinally disposed grooves 7. The side plates 6- are provided with enlargements 8 and 9, the enlargements 8 being located at the rear end of the plate 1, while the enlargements 9 are located intermediate the ends of .the plate 1. The rear edges of the enlarge ments 8 are inclined and. notched, as at 10, and provided with graduations, as at 11, the graduations corresponding to and disposed in longitudinal alinement with the notches 10, as shown, the graduations representing the number of yards or ranges at which the fire arm 4 can be accurately used. fronting faces of the enlargements 9 are provided with inclined grooves 12, the object of Which will presently appear.

Adjustably mounted between the side plates 6 of the attachment is a bar 14 having side ribs 15 adapted to engage in the grooves The con- 7 of the side plates 6. Pivotal ly connected to the rear end of the bar 14 is a section 16 carrying triangular shaped lugs 17 upon its sides for supporting the rear end of said section in the notches 10 of the enlargements 8.

The section 16 carries a rear sight 18 of a conventional form.

Theforward end of the bar 14 is provided with a pivoted section 19, and pivotally connected to said section, as at 20, is a telescope 21, said telescope being of .a conventional form having lenses and adjustments usually employed in implements of this character.

The rear end of the telescope is provided with oppositely disposed pins 22 for supporting the rear end ofa telescope between the en argements 9, said pins engaging in the grooves 12 of said enlargements. The forward end of'the telescope is secured in a bracket 23, slidably mounted upon the bar rel 3 of the fire arm. It is also necessary to slide the plate 1 upon the barrel 3, owing to the fact that the arms 2 are rigid. This is accomplished by removing the front sight of the gun.

Assuming that the fire arm or gun is to be shot at a range of two thousand yards, the section 16 is elevated, and the lugs 17 placed in engagement with the notches 10 of the en largements 8 corresponding to the graduation two thousand. The telescope 21 is then that the observer can look through the sight and the eye-piece at the same time Without inconvenience. When the rear end of the section 16 is elevated, the bar 14 is moved rearwardly carrying with it the section 19, and causing the rear end of the telescope to be elevated between the enlargements 9. The adjustment of the section 16 places the telescope 21 at the proper inclination for si hting an object through the same, the te escope being adjusted to properly position the lenses for sighting at two thousand yards.

It will be understood that the telescope will require adjustment to overcome atmospheric conditions and the variations in the strength or other conditions of the eye of the operator, while the sight mechanism will also be required to be adjusted to overcome 1 V windage, and such other conditions common to the operation of gun-sights.

It will be apparent from the fore oing description taken in connection with t e drawing, that I have devised a novel attachment for rifles and fire arms that can be constructed upon a large scale for'use in connection with naval and artillery guns for obtaining an accurate sighting upon an object.

The attachment is constructed of strong and durable metal that will not corrode or be susceptible to contraction and expansion.

I do not care to limit myself to the minor details of construction, as such changes in" the size, proportion and minor details of construction, as are permissible by the appended claims, may be resorted to without departing from the spirit and scope of the invention.

What I claim and desire to secure by Letters Patent, is

1. In an attachment for a fire arm, the combination with the barrel thereof, of a plate clamped upon said barrel, enlargements having grooves in its confronting faces and extending from said clamped plate,

notched enlargements carried by said side plates, a bar slidably mounted between said grooved side plates, a sight section pivotally connected to said bar and having lugs to engage in the notches of said enlargements, a section pivotally connected to the forward end of said bar, a telescope carried by said section and having its rear end provided with pins adapted to engage in the grooves in said enlargements, and a bracket for supporting the forward end of said telescope.

2. The combination with a fire arm and a telescope, of a plate carried by the barrel of said fire arm, enlargements carried by the rear end of said plate, and having notches formed therein arranged at an inclination to said plate, grooved enlargements carried by said-plate, a bar slidably mounted upon said plate, a sight section pivotally connected to said bar and adapted to be supported in the notches of said enlargements, a section pivotally connected to said bar and to said telescope, and pins carried by the rear end of said telescope and extending into said grooved enlargements.

3. An attachment for fire arms embodying a plate, a bar slidably mounted upon said plate, sections pivotally connected to said bar, a telescope pivotally connected to one of said sections, a sight carried by the other of said sections, means for supporting said sight section in an elevated position, and means for supporting the rear end of said telescope in alineinent with the sight of the elevated section.

In testimony whereof I afiix my signature in the presence of two witnesses.

FRANK KLOUSNITZER.
